Arapaima gigas

Arapaima gigas is the largest freshwaterfish in the world. It is therefore absolutely not suitable for our living room aquariums, but only for the very largest show aquariums. Since it is very aggressive towards conspecifics, it is recommended to keep it alone in an aquarium smaller than 5 meters, especially at a later age. It is also a real predator, so the company of smaller fish is not recommended.

Arapaima gigas was officially described by Schinz in 1822.

You can sometimes hear Arapaima gigas in the wild. They not only breathe underwater, but also regularly surface to take a breath of air. They do this so loudly that it can be heard over a great distance.

Synonyms: Sudis gigas, Arapaema gigas, Sudis pirarucu, Vastres cuvieri, Vastres arapaima, Vastres agassizii, Vastres mapae.
